Google Tech Talk (more info below) March 29, 2011 Presented by Cliff Click, Azul Systems. ABSTRACT Just what the heck is a JVM *supposed* to do? JVMs already provide a host of services. The 'J' part definitely slants the service selection and the 'V' part means that underneath the illusion there's a lot of really cruddy stuff. The success of these illusions has led to the real popularity of JVM...

Over the past several years Clearspring has developed custom distributed processing and storage systems for dealing with the billions of views our web products receive per day. A central part of this system is a tree-based storage structure that fills a useful middle ground between the datamodel-centric view of row oriented databases and the query-centric view more common with column oriented o...

Summary As Java continues to age, many developers ask how a language for general purpose & business computing would look if designed today. The result is Ceylon - a prototype language for the JVM which attempts to combine the strengths of Java with the power of higher order functions and declarative programming. This talk from QCon Beijing 2011, Gavin King introduces Ceylon for the first time. ...

Summary David Pollak talks about using Scala to write the Lift web development framework and his desire to write a productive framework that allows the developer to write concise code on top of a very strongly typed language. Bio David Pollak has been writing commercial software since 1977. He wrote the first real-time spreadsheet and the world's highest performance spreadsheet engine. Since 19...

Summary The last few years have seen a large upsurge in the number of alternative languages running on the JVM. Until recently, Java was the only serious language that ran on the Java platform, but this is now quickly changing with languages like Scala, Nice, Pnuts and Groovy being designed for the JVM, and language ports like Kawa, Jython and JRuby gaining headway as fully featured alternative...
